Thanks for the advice, Stephen. I've just been reading people's experiences with tall stands. I think you are right, I'll just leave it.I wouldn't recommend one at all.
Accidents happen - and when a horn gets knocked off an ordinary stand the damage can be quite nasty. When a sax takes a tumble from a tall stand things get much more serious.
I've seen quite a few horns that have suffered that fate. The last one was a lovely old Selmer. I spent a great deal of time putting the horn back in to shape - and when the client collected it I said "Ditch the stand - it's asking for trouble".
He ignored my advice - and some time later I got a message to say it had fallen off the stand again. I didn't reply.
I'm not terribly convinced my Hercules tenor stand is any good. I had to modify it to get a better, more secure angle on it...and every now and then I find that the sax slips and tilts sideways. If it does that on a tall version, it's not going to be good.
I might go back to my old K&M/Hamilton thingy.
